Urinalysis Tests

Sample Submission

Samples for urinalysis can be submitted in a clot tube, syringe, or other sealed containers. A minimum of 3 ml is required for microscopic sediment evaluation.

Tests Performed

  • Routine urinalysis
  • Urine hemoglobin/myoglobin

Coagulation/Crossmatch

Sample Submission

Samples for coagulation tests should be submitted in a sodium citrate tube (blue top) with the exception of FDP which should be submitted in a soybean trypsin tube (also blue top). Note: It is critical that tubes be filled properly. Sodium citrate and soybean trypsin tubes should be allowed to autodraw 2.7 and 2.0 mL respectively to insure exact anticoagulant dilution. Coagulation tests are batched and run daily at 10:00am and 3:00pm. If it is an emergency, please notify lab personnel.

Recipient samples for crossmatch or blood typing tests should be submitted in EDTA tubes (purple top). Donor samples can be submitted in EDTA or as blood bag segments.

Sample Submission

Samples should be submitted in an EDTA tube (purple top) for cell counts and microscopic examination, and clot tubes (red top) for chemistry analysis. CSF specimens and samples for chemistry analysis should be submitted in a clot tube (red top) for both cell counts/differential and chemistry analysis.

Tests Performed
